Thank you so much for this opportunity to try and be of service to you today.
I am a licensed attorney and will do my best to provide you an honest and accurate answer to your important legal question.
QUESTION: "What are my options now? I'm going into hearing with nothing but my request for change of venue but no defense for modification of support?"
ANSWER: First of all, please allow me to say that I am genuinely sorry for the circumstances. I can only imagine how incredibly stressful and frustrating this whole mess is for you. Alright, here is how this works. Frankly, this is ridiculous. It is patently unfair to expect you to defend yourself against a case where your hands are tied behind your back. Accordingly, I would encourage you to think along the following lines. Seeking a change of venue was fine, makes sense and was a logical move, but there is a more foundational matter at the heart of things. Meaning, without enjoying personal jurisdiction over you as a defendant/respondent, the Court utterly lacks the power to enter any Orders against you, period. In other words, I would think about a "death knell" approach, meaning the Court would never even get to the merits of the State's case. This means moving for dismissal of the case against you. In my estimation, such a dispositive motion represents your best and most favorable option given the circumstances you have described here.
My heart goes out to you, and I would be glad to continue our dialog as needed, so please remember to go ahead and rate my answer by selecting from the available choices. Doing so will not close your question. I will gladly continue interacting with you after wards for absolutely no additional charge whatsoever to you. Placing a bonus is entirely optional but always greatly appreciated to enable me to continue assisting customers in this venue.
I truly hope all works out for you.
